Processes and Services

Cowies Heat Treatment (Pty) Ltd trading as Metal Technology Engineering is a medium sized heat treatment plant in Gauteng and is uniquely situated in the heart of Alrode, Alberton and is easily accessible to a wide variety of industrial areas that surround it. It is a relatively small business but offers a wide variety of commercial heat treatment options.

These include…

•    Carburizing and Case Hardening
•    Hardening and Tempering
•    Austempering ( Steel and ADI)
•    Liquid Nitriding
•    Nitrocarburizing ( Tufftriding)
•    Nitrocarburize and Oxidize
•    Tufftride QPQ
•    Precipitation Hardening of Aluminium Alloys
•    Solution Treatment of Stainless Steels
•    Stress Relieving
•    Normalizing
•    Annealing

We also offer the following on a sub-contract basis…

•    Induction hardening
•    Vacuum Hardening
•    Plasma Nitriding
•    Gas Nitriding
•    Gas Carburizing

We currently have three carburizing/hardening salt baths each capable of heat treating approximately 200kg per hour. We also have an austempering facility and specialise in the austempering of ductile iron (ADI). Our liquid nitriding/nitrocarburizing facility consists of one salt bath with an oxidizing salt bath quench (oxynit). With oil, salt and water quench facilities we are able to heat treat a diverse range of engineering materials. We also have a dedicated Aluminium heat treatment facility with extremely tight temperature control and run precipitation hardening treatments on all heat treatable grades of aluminium on a daily basis. 

All our furnaces are connected via SPECVIEW SCADA software to one central computer where all data can be logged, recorded and analysed 24 hours a day. This system has proved invaluable with regards to process and quality control. We have a fully functional laboratory and are able to offer a variety of metallurgical services to complement the heat treatment which consequently improves our quality control and ultimately the service we offer to our valued customers.

Metal Technology Engineering will continue to provide quality heat treatment to its customers and with a philosophy of continuous improvement in all facets of our business, we hope to become the preferred supplier to all existing and prospective clients for years to come.

We look forward to being your top quality service provider.
